TARSONS WITH THE WORDS TRUST DELIVERED Tygon F-4040-A fuel tubing 3/16" ID x 5/16" OD — 5 ft, chemical-resistant translucent yello

Durable translucent Tygon F-4040-A fuel tubing — 3/16" ID, 5/16" OD, 5 feet — engineered for safe transfer of hydrocarbon-based fuels and lubricants.

This premium cut length of Tygon® formulation F-4040-A offers a flexible, chemical-resistant option when you need a short run of fuel or lubricant line. The semi-transparent yellow tube lets you visually confirm flow while the material resists swelling, hardening, and embrittlement that typical hydrocarbons cause in ordinary plastics. It is intended for non-potable fluid service such as engine lines, heating fuels, glycol-based coolants, and similar applications where compatibility with petroleum products is required.

How does this tubing stand up to gasoline and other fuels?

Tygon F-4040-A is formulated specifically to tolerate contact with gasoline, kerosene, heating oils, cutting fluids and many glycol-based coolants without degrading quickly. The compound minimizes material changes that lead to leaks or failures over time compared with generic tubing.

• Resists swelling, hardening and embrittlement from hydrocarbons
• Compatible with a wide range of petroleum-based fluids and lubricants
• Maintains flexibility across typical service temperatures

What are the temperature and mechanical limits I should expect?

This tubing performs across a broad temperature band and offers reliable flexibility rather than stiffness. Check your system’s pressure and temperature demands to ensure suitability; working pressures vary by tube size and application specifics.

• Working temperature range: -35°F to 165°F (-37°C to 74°C)
• Durometer (hardness): 57A for a soft, flexible feel
• Working pressure depends on installation and system; sized tubing reduces pressure rating compared to larger diameters

How does the translucent yellow color and clarity help in practical use?

The semi-clear yellow tint enables visual monitoring of fluids while providing quick identification among other lines in a system. It also offers limited filtration of ozone and UV light, which can slow some forms of degradation in exposed installations.

• See flow and detect air pockets or contamination visually
• Yellow color eases line identification during maintenance
• Translucence provides partial UV/ozone filtering for exposed runs

What typical applications suit this 3/16" × 5/16" tubing?

This cut length works well where short runs of fuel, coolant or lubricant must be routed with flexible, chemical-resistant tubing. It is a practical replacement for small engine fuel lines, heating fuel feeds, polishing fluid supply lines and other non-potable fluid transfers.

• Small engine and lawn equipment fuel lines
• Heating oil and kerosene delivery on short runs
• Glycol-based coolant transfer and workshop lubricant lines

Who is this for: Installers, technicians and hobbyists who need a reliable, short length of fuel- and lubricant-compatible tubing will value this Tygon F-4040-A cut piece. If you’re replacing small engine fuel hose, routing short heating fuel lines, or setting up coolant or polish delivery where a flexible, fuel-resistant tube is required, this 5-foot section provides a ready, OEM-grade option with clear visual monitoring and long-term resistance to hydrocarbon damage.
